REFRIGERATOB-CAR.

Specification of Letters Patent.

Patented Sept. 10, 1918.

Application filed January 3, 1916, Serial No. 69,779. Renewed March 19, 1918. -Serial No. 223,467.

To all whom t may concern:

Be it known that l, MAURICE B. DIETE, a citizen of thc United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Refrigerator-Cars, of whichthe following is a specification.

This invention relates to new and useful improvements in a refrigerator car.

The object of the invention is to provide a car of the character described containing ice receptacles and equipped with pipe cells through which the brine given oli' from the ice may be circulated around the` walls of the car, and further provided with means for circulating the air around said pipes and throughout the oar.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts au example of which is given in this specification and illustrated in the accompanying drawings, Whereinz- Y Figure 1 is a horizontal sectional view of the car,

Fig. 2 is a, vertical sectional view thereof,

Fig. 3 is en enlarged fragmentary side elevation thereof, and

Fig. s shows a view of a universal cou, pling connecting the sections of a drive shaft employed in the device.

Referring now more particularly to the drawings wherein like numerals of reference designate similar parts in each of the figures the numeral 1 refers to the car hav-v ing at each end thereof ice receptacles 2, 2, beneath which are the brine receptacles 3, 3 arranged to receive the brine given oli from the ice, said last mentioned receptacles being connected by means of the conduit f1. Leading from the betteln of one of the brine revlceptaclcs is the pipo 5 which is coiled around Aunderneath the root' of the car and returns to and discharges into thc upper part of said receptacle 3. The car is mounted upon the usual trucks 6, fixed to the axle of onc of which the sprocket `wheel i' which drives the sprocket chain 8, which in turn operates over and drives the sprocket whccl Si, this lust mentioned whccl boing mounted in a suitable bearing 1() carried by said truck. The inner side of the sprocket wheel Si has a bcvcl geur face 11 which meshes with and drives the bevel gear whccl 12 fixed upon the lower cud of the drive shaft, This shaft is formed of sections 13, 13, 13, which are united by means of universal couplingsll, 14, and said shaft has suitable slip joints as 15,'15 provided to permit a. certain amount of variation in the length of the shaft,

lrojecting inwardly from one side vof' the car is the spindle 16 whereon is mounted theA bevel gear wheel 17 which is in mesh with and driven by a bevel pinion 18, fixed upon the upper end of' said drive shaft and the pulleys 19 and 20 are integral with said gear wheel 17 and over these pulleys operate the lrespective belts 2l and 22, the former of which drives the pump 23 and the latter of which drives the fan 24. This pump is provided to drive the fluid through thc pi )e 5 and the fan is connected to one end of the air pipe 25. This last mentioned pipe extends along between the coils of' the pipe 5 and is provided with a row of lateral orifices 26 along each side thereof. When the 'car is in motion the mechanism just dethe coils of the cooling pipo 5, thus utilizing more nearly the entire value of the ice and giving. additional refrigeration to the car thus equipped.

lVhat I claim is:

1. A car mounted upon trucks and having a receptacle containing a coolingv fluid, a conduit communicating with said receptacle and passing through the car, a pump for driving the fluid through said conduit, an air pipe having discharge orifices arranged Vadjacent said conduit, a fan for forcing the uir through said pipe against said conduit, und means in operativo connection with said trucks and driving said pump and fan.

2. A car mounted upon trucks, an icercvccptac'lc arranged at .each ond thereof, a

brine receptacle in communication with each ice receptacle, said brine receptacles bcing connected, a fluid vconduit leading from the lower portion of one of said brine receptacles and being coiled adjacent the wall there of and returningto and discharging into the upper portion of said brine receptacle, a

pumpl for forcing the Huid through said In testimony whereof have signed my oondmt, an fur pipe hnvmg discharge ounnmo to thus spemhcnhoh m the presence of hoes arranged :uhgucont 1h@ coals of amd two 5ubsc11bmg wxtlmssv;
